internally, define plain syscalls, if missing, as their time64 variants

this commit has no effect whatsoever right now, but is in preparation
for a future riscv32 port and other future 32-bit archs that will be
"time64-only" from the start on the kernel side.

together with the previous x32 changes, this commit ensures that
syscall call points that don't care about time (passing null timeouts,
etc.) can continue to do so without having to special-case time64-only
archs, and allows code using the time64 syscalls to uniformly test for
the need to fallback with SYS_foo != SYS_foo_time64, rather than
needing to check defined(SYS_foo) && SYS_foo != SYS_foo_time64.
